AUGUSTUS STEIGER COOPER, oir-BERKELEY, OALIFORNIA.

Be it'known that I, AUGUSTUS STQLGER COOPER, a citizen ofthe United States, residing at Berkeley, county of-Alameda, State f California, havefinve'nted certain new `and useful Improvements in'Separators for Gas,

Oil', Water, and Sand; and I hereby declare'.

the following to be a full, clear, and exact description of the same. My invention relates -to thatzclass of separators used in connection with gas andoil wells well-pipe. i

by which a separation is effected of the several constituents of thecontents issuing from In thatprocess which I set forth in a contemporaneous a plication fora patent a por-tion of the gas om the well is used repeatedly as a -lift or pulverizer to relieve the well of oil and water by raising or assisting to raisethem.- The contents of the Vdischargepipe, composed of gas,ioil, water, sand, and

. silt, is forced into a vessel included in the pressure system, wherein the constituents are separated without affecting the general pressure in the system and the as recovered and takenv .to-the compressor to e used again in part as the4 lift or ulverizer to relieve the well, the surplus oft e gas being conducted away for any useful purpose.

It is `to such a separator that my finvention relates, its object being to efiiciently se arate and deliver the gas, oil, water, and sand fioma pressure system used -in lifting or pulverizing the oil and water and relieving the Well of them.

To this end my inventionconsists in the no vel separator which I shall now describe by referenceto the accompanying drawings,

atented March' 20, 1996.

pori-.ion of the cylinder is a' water-'jacket E, and from the top of the cylinder leads the gas-pipe F.to the compressor.

The operation is as follows: Gas, oil,'water,

silt, and sand are forced from near the bottom 'of Ithe Well by the compressed gas and pass through the pipe B into the cylinderA. Entering the cylinder underpressure tangentially to its circumference, the material is thereby given a rotary motion, which separates the constltuents ,conformably to their specific gravities.

The gas rises and passes from the cylinder through pipe F to the compressor. The sand seeks the outer circle and vdrops down to the bottom, as is indicated by S.' The water W lies on the sand, while the oil O lies on the water. When these constituents. accumulate to raise the oil to a certain level, the float c y rises and opens the cock c, thereby permitting the oilto be forced out by the internal pressure in the system through the pipe C to I "ters Patent, is-,
